Can/Could you please.. “请你···好吗？”/“你能/可以···吗？”，用于提出要求或请求。常用答语有： 2. Can/Could I..., “我能···吗？”，用于请求对方允许自己做某事。常用的答语有： 3. 表示现在的能力用can, 表示过去的能力用could。此时could是can的过去式。 Practice: Choose the best question to complete each conversation. Make up conversations for each setting, using can or could Production: Imagine that (1) you can’t be at home when the delivery comes. You want to ask your neighbor to help receive it. / (2) you plan to play basketball in the park. You want to ask your friend to join you.

板书设计
课后反思 本课通过情景对比和分层练习，帮助学生掌握了can/could的用法。情景导入直观呈现礼貌差异，激发兴趣；3a-3c练习层层递进，强化应用；乔迁派对情景提升了迁移能力。但部分学生对“用can回应could”仍混淆，词汇应用单一。
